基于ARM的Embedded Internet的实现

GPRS and SMS Technique in Embedded Internet

为解决远程嵌入式设备以无线方式接入Internet的问题,需要实现Embedded Internet(EI).EI的实现有多种方式,其中在基于ARM硬件平台的微控制器中引入能够处理多个内部task和多个外部输入源数据传递的嵌入式操作系统-μC/OS-Ⅱ是一个较好的选择.文中介绍了实现EI的关键技术,包括基于ARM的EI的硬件设计技巧、嵌入式操作系统μc/OS-Ⅱ移植、μc/OS-Ⅱ中实现GPRS和SMS技术的编程技巧和其他应该注意的问题.文中还给出了解决软件调试过程中发生的典型问题的方案.

The embedded Internet （EI） based on ARM processor has been implemented in order to solve the connection of remote embedded equipment and the Internet. There are many ways to realize the EI. A better way is to utilize the embedded operation system-μC/OS-Ⅱ which can deal with multitask and multi outer data sources based on the ARM. The design of hardware, the transplant and the programming of the μc/OS-Ⅱ in EI is the focus in the paper. How to implement the GPRS and the SMS technology in μc/OS-Ⅱ is also introduced. And, some important and typical problems and their resolvents have been mentioned.
